Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

Among the consequences of a crowded electromagnetic spectrum is noise—a lot of it—created mostly by an influx of wireless and other emitters generating a cacophony of signals of varying frequencies ...
